Sheesherz!
This truck may live longer than me! I bought my '90 with 76k on it, I've already put 10 more under her belly, but she's been parked since fuel went up, except for a dismantling job we did a few weeks ago. I don't need a truck every day.
Someone asked about other diesels. I have a '87 Mercedes 300D the big sixer! Has an exhaust leak in it since day one under my care.... or lack of. Bought it as a throw away, odo reads almost 300k, but it broke within the week of me owning it. I think the used car lot jury rigged it to work..... who the heck knows how many miles are really on this thing. It's my daily driver, 80 miles/day minimum and I drive it all 7 days a week. I've had it for two years now....that's about 55k under my watch. Only thing I've done is, I rebuilt the injectors and changed the oil regular, run some nasty azzed waste fuel through it and she won't quit!! The body is falling off the engine, but no rust! Go figure! You can hear the steering 3 miles away, kids are embarrassed when I drop em off to kewl land known as skewl.... yet I love this rotten little beast. Best brakes on any car I've ever driven.
